2020 brought unprecedented events on the human race which shook the entire humanity, humankind has witnessed, the deadly COVID-19 pandemic, Beirut explosion, Russia and
Mauritius oil spoil incident, locust swarms in east Africa & several parts
of India & Asia, flood, cyclones.
After these disasters, entering in September 2020 another
dreadful disastrous wildfires have blanketed swaths of the West Coast with
unhealthy smoke, complicating efforts to fight the blazes and find dozens of
missing people in Oregon as a wildfire that have torched millions of acres across
the west continue to burn, the death toll rising to 20 and smoke choking
residents in cities far from the fires.
According to the California Department of Forestry and protection. A total of 7,718 fires have burned 3,354,234 acres more than 3% of the state’s roughly 100 million acres of land, making 2020 the largest wildfire season recorded in California history.
According to IQAir.com, the smoke pollution from the
wildfires has left Oregon’s largest city, Portland, with the worst air quality
in the world, followed by San Francisco and Seattle.
Factors
of such disastrous wildfire
Usually, the three elements are the main factors for the
creation of wildfire: Fuel, Oxygen, and heat. Most of the time drought
conditions peak and something as small as a spark has the potential to create a
large wildfire with devastating consequences.
Although fire can occur naturally from the sun or a lightning
strike, most wildfires are started by human carelessness. Un extinguished
campfires, lit cigarette butts, improperly burned debris, and arson are responsible
for 84% of wildfires started.
Man-made wildfires have triples the fire season from 46
days to 154 days with a staggering cost of $2 billion.
United Nations Already warned, that five years from 2016 until
this year will very likely be the hottest such period yet recorded. Both Oregon
and California have warmed by more than 1 degree Celsius since 1900, nine of the world’s 10 The warmest years on record have occurred since 2005.
California has seen other disasters like drought over the
past decades which has killed millions of trees and turning them into potential
fuel for the fires, and the mountain regions that are normally cooler and
wetter has dried out more rapidly in the summer.
Scientists already forecasted that western wildfires
would grow in size, scale and impact- but their predictions are coming fruition
faster than expected.
How harmful
a wildfire can be?
Consequently, wildfire harmful impacts can have immediate
and long term effects on the quality of rivers, lakes, and streams. The loss of vegetation,
the ground’s soil becomes hydrophobic and stops the absorption of water. And
this inability to absorb water stimulates the transportation of debris and
sediment into larger bodies of water to further polluting valuable and essential;
resources.
Fire flash floods become a threat and allow the
introduction of heavy metals from ash and soil to infiltrate waterways. Filtering
these water sources can be costly as well as time-consuming,
Wildfire occurs in a different time of a year when the temperature fluctuates, wildfire significantly impact on vegetation.
Plants in
the forest or smaller trees are usually destroyed by wildfire, while larger
trees are able to survive as long as the fire doesn’t spread into the
canopy trees.
The deadly flames from these forests destroy the food
sources and homes of wild animals, threatening their survival. For plants and
trees that can survive the flames, they are susceptible to disease, fungus, and
insects due to their decreased resistance following burn injuries.
Along with forest burns, a large amount of smoke is
released into the atmosphere. These harmful smoke particles are typically small
and made up of gases and water vapor.
The biggest threat from wildfire, is air pollution from fires
have the potential to travel a great distance, and oftentimes may pose a threat to
human health. These small particles can become lodged deep within the lungs,
making it difficult to breathe as well as placing additionally it can lead to
heart disease. Wildfire produces a high amount of carbon monoxide, which too can
lead to different kinds of diseases.
How climate
change promotes wildfires?
The year 2020 has seen unprecedented wildfires cause havoc
around the world. Recently Australia battles its deadliest bushfire on record,
while parts of the Arctic, the Amazon, and central Asia have also experienced unusually
severe blazes.
In 2019, the world witnessed the Amazon its third-largest
fire on record, while intense blazes also raged in Indonesia, North America and
Siberia, among other regions.
many analysis released this year, they show that,
globally, climate change is driving an increase in the weather conditions that
can stroke wildfires.
However, despite a growing field of evidence suggesting
that climate change is making the conditions for fire more likely, researchers
finds that the total area burned by wildfire each year decreased by up to a
quarter in the past two decades.
Scientists found a cast range of influential factors,
including climate change, human land-use, and political and social motivation.
Wildfires
increasing across the globe
Climate change increasing the risk of hot and dry weather
in several parts of the world, it may seem prudent to assume that the global
areas burned by wildfires each year is increasing, but many research papers
looking into wildfires at a global level has come to the opposite conclusion.
A paper released in the journal Science found that, globally,
the areas burned by wildfires decrease by 25%between 2003 and 2015.
Wildfires
can really change in the future?
If climate change continues to drive temperature rise and
more uncertain rainfall in many parts of the world, meaning that the number of
days with: fire weather” – conditions in which fires are like to burn is expected
to increase in the coming decades.
According to the study covered Carbon Brief, they found,
by the middle of the century, there could be a 35% increase in the days with a
high danger of fire across the world, on average – if little actions are taken
to tackle climate change.
Many regions are likely to see the highest increase in days
with extreme fire weather in this very high emissions scenario including the western The US, southern Australia, the Mediterranean, and southern Africa.
Many other studies show this risk of fire weather is
likely to change in different world regions.
In California, climate change will further amplify the
number of days with extreme weather by the end of this century. However, if
efforts are taken to limit global warming to below 2C, which is the goal of the
Paris Agreement, this would substantially prevent that increase.
In 2018 a landmark special report from the intergovernmental
panel on climate change concluded that limiting global warming to 1.5C rather 2
C would “reduce” the average wildfire risk worldwide.
It’s a crucial issue because it not only climate change
is controlling future fire risk, it’s also the interaction of humans and
climate change. It is although possible that efforts by humans to suppress
wildfires could stem increases in the area burned by fire, despite the
increased risk pose by climate change.
